Oracle 11.2.0.3 on Linux_X86-64 April 2012 Critical Patch Updates
I have installed Oracle 11.2.0.3 on Linux_X86-64 (downloading the files that included the latest patch 0404530_112030_Linux-x86-64_xof7.zip). My Oracle Support news indicates that April 2012 CPU is available for patching and the notes indicates Oracle Database Critical Patch Updates and Patch Set UpdatesThe Database Patch Set Updates and Critical Patch Updates that are released each quarter contain the same security fixes. However, they use different patching mechanisms, and Patch Set Updates include both security and recommended bug fixes. Consider the following guidelines when you are deciding to apply Patch Set Updates instead of Critical Patch Updates.Critical Patch Updates are applied only on the base release version, for example 10.2.0.4.0.Patch Set Updates can be applied on the base release version or on any earlier Patch Set Update. For example, 11.1.0.7.2 can be applied on 11.1.0.7.1
